mummia-LOADING DEVICE Be it known that I. lxuzrr H. RifooLPH, n citizen of the United States of A'merica, residing nt Pershing. in the State of (lltlnlnnnn. hure invented new und useful lluprorements in 'lnnkCnr-Loading Devres.

. o'f which the following is-n speeilicntion.

'use in ronnertion with Aprovided with n loading und unlonding The object ot the invention is to provide means for furilitnting the loading und unloading of tnuk earn designed for the transiortntion of gasoline and other volatile und mflnmnnlhle oils und liquids, adapted for tunl: cnrs of the in eonnnon 15e. nud more esperinlly to provide r. derive for the purpose indiented whieh is npplirnhle to that form of the eoinmerrhd type of tunlt enr wherein the. dome is serured exteriorly to the hull of the. enr und ronnnuuirntes therewith through a manhole. in the hull or shell us distinguished from those enrs in wlrirh the domel is formed :is u pnrt or Continuntion of the wall of the hull.

'further ohjert, oi' the invent-ion is to provide simple und etiirient menus whereby the Connex-tion of the Aloading und unloading' pipeor drum muy he eonneet'ed with the shell of the hull und the. upper wall or tup of the doute` und whei'ehy the lower end or the outlet und inlet T of the loading :ind unloudinll.; drum may he supported in stp-.h u wuy als to nvoid st comun-tions und yet in un lutioii with the bottom or to tln` end thnt the drainage the relnoxnl of :weumulutionel of or the like duly he tnrilituted.

ing; provided with u manhole 13 adapted when the enr is in transit to he ciosed by a suitable plug 1t ns in the ordinary ractufe. There is also provided nn oil or c rain vulve 1.3 in the bottom or floor o' the hull l roi-ered hy :x guard strap 16 through which extends the valrerod 1T having 'a hand wheel 15 loented in the dome for fcilitating the unsenting of the vulve when it is desired to drain thgx car. The body portifrmzglrrum- 19 of the load lng und unloadingr pipe` is rovided at its lower end with the usual 20 su ported hy u .strap 2t which muy be :ittuehet to 'the guard stru i or enge 16 covering` the outlet or Hoor vu ve, so that the lower end of the snid loading und unloading pipe is supported uhuve und' `out; of rontnct nv-ith und renee' in unohstrurtive relntion toy the bottom or floot-.ot the tank or cnr hull. so ns not to interfere ,with the drainage of the liquid und sediment 'in the our to Vthe outlet vulve when the lutter has heen nnseuted or opened.

tion of the contents thereof.

Aside from its highly eil'n'ient function as u london: menne. the in ventlon combines for'snving the gnso ill-us 1t is transhquid passing,

liue or other intlulnniulili\ felred to the tnnle` volatile ducing;r coupling from the upper reduced section 2G into the body portion 19 of the drum, the pressure is materially reduced in the latter and as the liquid passes into the car there is very litt-le .agitation and wha-t gases form in the drum are readily concentrated. In i ca-r having a. capacity of 'approximately eight thousand "allons, a saving of from one hundred and lifty to two luuidred and fifty gallons results from the employment of a construction sucli as is herein described.

Having described the invention what is claimed as new and useful iszl. The combination with a, tank car having u. hull and a dome snrmoiinting the hull Vof e pipe having adrum.' or enlarged mem` beilocated in the hull, a diametrically reduced member arranged in the dome, and a reducing couplin supported h the division wall between themll and the c ome and connecting the adjacent ends of said pipe membei'.

2. The combination with a tank cai' having a hull und a dome sui-mounting the hull, of u pipe having a drum or enlarged inembei' located in the hull, n diametrieally reduced member arranged in the dome, a resuppoitod by'the wall be,- tu'ecn the hull and the dome and connecting the adjacent ends of said pipe members, and n T carried at the lower end of the drinn or l enlarged member .adjacent to but out of contact with the bottom wall of the hull.

3. The combination with a tank car baving a hull and a dome surmountiug the hull` 'of n pipe having a drum or enlarged ineinber locatediu the hull` a diaiiicti'icall)I reduced member arranged in thc dome. u. reducing: coupling supporti-.d by the wall between th'.l hull and tliedomc and connecting the adjacent ends of said pipe nwlubers, and :in outlct T carried at the lower end of tbe drum or enlarged member and vialdingly snpporlrd above and out ot' contact with the bottom of the bull.

4. The combination with a tank cui' having it hull and a domo Hui-mounting thc hull, of a. pipe haring a drum or \=nlargcil menibei' locator] in the hull, a dianietrically reldrum or enlarged portion duced member arranged in the dome, a reducing` coupling supported by the Well hetween the hull and the dome and connectinuf the adjacent ends of said pipe members, sai

coupling consisting of a flange nipple having upwardly and downwardly extending collars, a reducer connecting the upper end of the drum or enlarged member with the lower collar, and a lock. nut engaged with' the lower end of the reduced member and in abutting Vei'igagement with the upper collar of said nipple.

5. The combination with a tank car having a hull and a dome surmounting the hull vand 4in communication' therewith by. a manhole iri the shell of the hull, said dome heing provided with a manhole tted with a removable plug, and the hull being provided with :i bottom ventvalve and a guard strap spanning the sameno a ioading and unloading device consisting of a pipe having a arranged in the hull and provided at its lower end with an outlet T, and a reduced upper member arranged in the dome and provided at its upper end with iiunion for attachment of a loadingnozzle, :i reducer interposed between the adjacent extremities of said inembers of the pipe, and a strap supporting the lower end of the drum and attached to said guard strap.

(S. The coiiibnatioii with :i tank car haviupr a'liull and a dome snimounting the hull and in communication therewith by a manhole in the shell ol the hull, said domo being provided with a inanliolc fitted with a, removable plu". and the hull being provided with a bottom vent valve and a guard' stra spanning the same, of a loading and niilomlin ir device having relatively enlarged and rcduccd pipc. sections arranged respectively in the bull and dome and coi'inocted by a reducer arranged adjacont to the top of the hull and supported thcrcon by a flange nipple, and a vacuum vent pipo in communication with tbc interior of .said donuf.'
